The Associated Press | March 29, 2014 Kentucky's Cauley-Stein doubtful for the regional final against Michigan Share INDIANAPOLIS -- Kentucky's Willie Cauley-Stein had a walking boot on his left foot Saturday and head coach John Calipari said the sophomore was doubtful for the regional final against Michigan. Cauley-Stein left Friday's win against Louisville with about 13 minutes left in the first half and did not return. He told trainers he felt something pop in his left ankle. The 7-foot Cauley-Stein, considered a top-15 pick if he decides to leave for the NBA after this season, averages seven points, 6.2 rebounds and 24 minutes a game for the eighth-seeded Wildcats (27-10). They play second-seeded Michigan on Sunday with a trip to the Final Four at stake.
